    摘要: The solution is directed to a bleacher step access prevention system. The system is configured to be locked in place over a stairway of a retracted bleacher system in order to prevent climbing of the stairway when the bleacher system is in a retracted state. Certain embodiments are configured to accommodate handrails of the bleacher system so that handrails do not have to be removed from the stairwell when the bleacher system is in a retracted state.

    摘要: A telecommunication and multimedia management apparatus and method that supports voice and other media communications and that enables users to: (i) participate in multiple conversation modes, including live phone calls, conference calls, instant voice messaging or tactical communications; (ii) review the messages of conversations in either a live mode or a time-shifted mode and to seamlessly transition back and forth between the two modes; (iii) participate in multiple conversations either concurrently or simultaneously; (iv) archive the messages of conversations for later review or processing; and (v) persistently store media either created or received on the communication devices of users. The latter feature enables users to generate or review media when either disconnected from the network or network conditions are poor and to optimize the delivery of media over the network based on network conditions and the intention of the users participating in conversations.

    摘要: A method for assembling a theater and a theater. The method includes assembling a modular auditorium on a surface within a building structure by providing a plurality of nominal inventory portions. Each nominal inventory portions includes a prefabricated base portion, and a prefabricated tier section for assembly to the base portion. The prefabricated base portion is positioned on a ground surface of a public performance space. The prefabricated tier section is fastened to the prefabricated base portion to form a self supporting structure that does not require lateral support from a building structure other than the ground surface.

    摘要: A scissor lift (100) for use in a stage assembly includes a base portion (110) configured to be supported on a floor or other support surface and a top portion (120) configured to support a platform. A scissor arm assembly (130) connects the base portion (110) and the top portion, and a rigid chain lifting system (150) comprising a rigid chain (151) connecting the base portion (110) and the top portion (120). Extension and retraction of the rigid chain (151) causes the top portion (120) to rise and fall with respect to the base portion (110). The use of a rigid chain lifting system (150) means that the scissors (130) are provided for guidance rather than applying load. The scissor lift (100) can be used in conjunction with one or more passive scissors (200), couplable to the scissor lift (100).

    摘要: Arena apparatuses for staging a sport and methods of using and constructing same. The apparatus includes a floor and a wall, a bottom end of the wall located proximal to a floor perimeter, the wall extending upwardly and outwardly from the floor perimeter's vertical plane at an angle of greater than fifteen and less than sixty degrees. Alternate apparatuses include a floor frame for supporting a covering; a wall frame for supporting the covering, a bottom end of the wall frame located proximal to a floor frame perimeter, the wall frame extending upwardly and outwardly from the vertical plane of the perimeter at an angle of greater than fifteen and less than sixty degrees; and the covering for covering the floor frame and the wall frame to form a floor and a wall.

    摘要: A spectator hall at racetracks includes a roof with an inner ceiling decreasing in height from the racetrack, an opening directed to the racetrack, a back wall, a number of seats arranged with increasing height from the racetrack, at least one loud speaker at the ceiling near the opening, and an invisible front wall covering the opening. The invisible front wall is made from a stable material like glass or acrylic polymer, and is mounted stiffly e g by stiffening bars.
